Yeah it’s a circular reasoning fallacy they like to trot out. our morality is also subjective, not objective, this would also be the case even if they could demonstrate it came from a deity.
Good question, the obvious answer is that what we call moral are subjective choices we make, and they’re relative as well. This one is easy to test, is murdering babies immoral? if the answers yes then the deity in the bible is an immoral monster, or you’re about to hear another special pleading fallacy.
Fine tuned is a metaphor scientists use, like evolutionary biologists saying something like an eye has the appearance of design.
No, religious apologetics is relentlessly disingenuous, thus the kind of contradictions you are highlighting in their rationale.
Exactly, the apologetics is like insisting a puddle must be designed, because the hole fits the water perfectly and vice versa.
Thinking can be entirely subjective, if you start with an immutable belief, then bend everything to it, then the thinking process is largely redundant as far as the result is concerned.
